How to read or filter notify message

Hi with current sample it alway read from start when start, is there anyway to filter the min/max time or just ignore the previous recevied notify, tks
import TikAPI from 'tikapi';

const api = TikAPI("myAPIKey");
const User = new api.user({
    accountKey: "DemoAccountKeyTokenSeHYGXDfd4SFD320Sc39Asd0Sc39A"
});

(async function(){
    try{
        let response = await User.notifications();

        console.log(response?.json);

        while(response){

            let min_time = response?.json?.min_time;
            console.log("Getting next items ", min_time);

            response = await Promise.resolve(
                response?.nextItems()
            );
        }
    }
    catch(err){
        console.log(err?.statusCode, err?.message, err?.json)
    }	
})();
